For centuries, the Northwest Passage, the long-sought sea route connecting the Atlantic and Pacific Oceans through northern Canada, was a holy grail of Arctic exploration. Even now, sailing through it isn’t guaranteed. Mark Synnott, a National Geographic Explorer, writer, and adventurer, attempted to sail his own boat through the Northwest Passage to retrace the doomed 1845 expedition of British explorer Sir John Franklin. None of the Franklin expedition’s 129 men made it home, but what exactly happened remains a mystery.

Playback: Modern Lives, Ancient Caves
There’s a lost continent waiting to be explored, and it’s right below our feet. We’ll dig into the deep human relationship to the underground—and why we understand it from an instinctive point of view, but not so much from a physical one. (Hint: We’re afraid of the dark.) In an episode originally published November 2021, National Geographic photographer Tamara Merino will take us subterranean in Utah, Australia, and Spain, where modern-day cave dwellers teach us how to escape the heat.
